Same UV ratio for different objects in the same uv space

Alex262

I'm using 3ds Max and I have "n" objects, each unwrapped on it's separate uv space. Now I need to rearrange the uvs so that all of them fit into one uv space. I must not attach the objects into one. While the unwrap modifier is on top of several objects features like rescale elements, pack uvs or relax won't work for all the objects at once but for each object individually. How can I rescale the uvs so that I'll end up with a constant uv ratio other than manually per object? Do you know any plugin that can help in this case?

Textools should be able to do that? http://www.renderhjs.net/textools/

Or PolyUnwrapper, I think (it's paid, but it's really handy). http://www.polytools3d.com/polyunwrapper/

UV Layout is also good to create a even texel density

Thanks for the quick replies. I tried Textools, more specifically normalize shells and didn't work for multiple objects. Are you sure that it can do the job? A few details would be very helpful.

Unless I'll have no other choice left I will look only for free solutions. I'm very happy with the default tools for unwrapping provided by Max, this is the only problem I have in this area and I don't really want to buy a plugin just to solve this. Eventually I want to manually arrange the islands anyway so even a script may do the job. I just want the "rescale elements" feature to work for multiple object as if they were one.

Just tried PolyUnwrapper and it works with multiple objects.

Indeed, I tried the demo but I'll only note it as a last resort, still looking for a free plugin/script that preferably handles only this function.

If I'm using textools and can't merge the objects to do this, I use the get/set button to pick the density from one object and then apply it to the others. It's located next to the normalize tool.

Thanks, I made a quick test and looks like it's exactly what I was looking for.

PolyUnwrapper is worth every cent IMO. There're just 2 or 3 functions I regularly use that require textools to still be installed.
